virtualization for dummies

In recent years, the explosive growth of Business data volumes (mail data, applications, business data, special confidential data, and so on) has been accompanied by an increase in storage capacity and data management difficulties, coupled with the growing popularity of virtualization, which will face an unprecedented change in the enterprise storage environment The importance of storage virtualization is b

Server virtualization is said to be the most significant way to improve enterprise operation efficiency, reduce IT costs and reduce environmental carbon emissions. It is said that the effective application of virtualization technology can reduce server energy consumption by up to 82%. Unfortunately, many enterprises that accept server virtualization have not achi

Hardware and software procurement needs to be as strategic as possible as the current global market uncertainty and corporate scrutiny of IT budgets are stricter than ever. Many companies have turned to virtualization to do more with limited IT budgets and to reduce technology costs. Organizations are recognizing that storage and server virtualization can significantly reduce the benefits of hardware, power

The boom of virtualization technology swept through the IT industry in the 2007. There is no doubt that the rapid development of server virtualization has also driven the process of storage virtualization. According to the definition given by IDC, virtualization is moving from 1.0 times to 2.0 times. The mobility of da

With the increasing demand for application integration, more and more users hope to improve resource utilization by integrating or sharing physical assets. The pooling of physical resources in the data center can not only increase by 50% ~ 60% utilization, and rapid deployment and re-deployment of resources, while also reducing physical equipment, cables, space, power, cooling, and other needs, it can meet the rapidly changing business development needs. The Network

Server virtualization is becoming more and more common, and many companies are trying to run their existing business in a virtualized way--virtual multiple instances on a physical server, each isolated from each other as if they were using a real host, and so is network virtualization. Several network environments are virtualized on the same physical link and isolated from each other; Network

Fully integrated network virtualization technology (1) Server virtualization technology changes CPU, memory, disk, I/O, and other hardware into a "resource pool" that can be dynamically managed, thus improving resource utilization and making IT more adaptable to business changes. IT systems are composed of network server storage and many other factors. Partial innovation does not bring about an overall upg

In the previous article, we mentioned the general classification of virtualization technology, which is divided into 3 categories: full virtualization, semi-virtualized, and hardware-assisted virtualization technology. And the main virtual body of our virtualization technology is our hardware CPU, memory and IO, so how

The enterprise data center virtualization introduced in the past few years has become a widely accepted concept today. The latest virtualization technology can help enterprises increase efficiency, reduce costs, and fulfill their commitment to reducing carbon emissions. However, when it comes to a real virtualized data center and server virtualization, so that mu
